The surtending between the pairs of rolls, however 1 have provided a guide which may be located within this minimum space and be supported from the overarms between the working, surfaces of the roll and which arms support the bearings for the different rolls and the guide which I provide does not interfere with the removal of the rolls, for the piecing up of broken ends, should such broken ends occur. I have also found that where a guide is employed which cannot move with reference to the position of the travel :of the yarn over the roll or shift with the travel of yarn that it is desirable to provide a movable guide which will adjust itself to thiscenter and thus accommodate itself to machines in which adj ust ment of the rod between the front pair of rolls and nextadjacent pair of rolls cannot be had; and the following is a detailed description ofthe present embodiment of this invention illustratingthe preferred means by which these advantageous results may .be accomplished. v l I I The drawings show the invention as applied in a mule spinning frame inwhich .9 is the stationary frame part ofthe mule spinning machine upon which there is mounted aphirality of bearing blocks supporting the lower driven rolls 11, 12, 13, 14 and15 which extend a considerable length and are formed with reduced port-ions between their working surfaces as shown in Fig. 1. These are each suitably driven from one end of the machine in the usual manner. Overarms 16 are provided at spaced intervals along thelength of the machine upon which blocks 17 are secured in adjusted position and each block is provided with a groove 18 in which the reduced end portions of the upper rolls 19,20, 21, 22 and 23 are'supported and rest by their own weight upon the corresponding lower-"rolls. The roll 19 is of large diameterto press with sufficient weight upon the lower roll 11, while the upper roll 23 of the front pair of rolls also of large diameter for this same purpose, and in some instances additional weight is provided. upon the upper front roll. by means of the arm 24 pivoted as at 25 at the back of the machine and pressing upon the front roll 23 by'its own weight and also through links 25, 26, lever 27 and weight 28 which may be adj usted. along the lever 27 to rest in any suit able notch 29.

The remaining rolls act as slip'rolls and carry the yarn along between nips. Clearer roll 30 for the roll 23 and clearer 31 for the, roll 10 are provided to pick up any waste or accumulation, or short fibers on either of. these rolls which may collect. The clearer 31 is held in engagement with the lower roll 15 by afmember '32 pivoted on shaft 36 and weighted by its enlarged end 33. The clearer block 34 engages the roll 14 and is similarly held in engagement by alever 35 pivoted as at 36 and forcing the block 34 into engagementwith the roll 14 by reason of its enlarged end 37 forming a weight.

As the yarn travels through the rolls the curl of the fibers often fray and form a waste whichcollects upon the rolls such as the front rolls 15 and 23 or thenext adjacent set of rolls 14 and 22 which it is the purpose of the clearers to pick up, and in order that these fraying fibers may be forced back into the yarn by an ironing process I have supported an elongated member 40 in the form of a rod or the like between the pairs of rolls 14 and 22 and 15 and 23 which must be of very thin and small construction by reason of the constrict-ed space between these pairs of rolls which run with their surfaces just clear of each other. And in order to support this elongated member or red 40 from the overarm 16 I provide a yoke 41 having an opening 42 to receive the overarm and be held in adjusted position thereon by a set screw 43. Thisyoke or support has the elongated member or rod secured thereto in any suitable, or desired manner such as by a rivet 44 assh own in Fig. 4. i

The elongated member or rod 40 is notched at intervals as at45 and in certain of these notches l: have slidably supported a guide 46 which is shown in Fig. 6 in perspective and consists of a body 51 having a flaring notch portion 47 to receive the yarn that is drawn from the back to the front'of the machine which serves to condense and iron the fibers or press them back into the strand or yarn. Thisguide is provided with arms having slots 4'? therein which receive the portions 48 adjacent each side of "the notch 45 and slidably mount the guide in position on the rod, permitting it freedom of sliding movement limited onlyby the sides 49 of each of the slots. v

The arm portions 50 of this guide are re tained against lifting movement by pins 52 at either side of the notch which extend over the arms 50 and prevent the guides from being lifted from its assembled position with the rod. By reason of this construction-oi guide a-nd'its sliding movement onthe elongated member or rod,'the same will centralize itselfwith reference to the location of the yarn as it moves over the roll and thus pro vents any sharp kinks or twists in the yarn and also will, if suiiicient pressure is exerted 1.
